number of unstable particles to decay to half that number of particles.) This fact is used extensively for archeological and biological dating of old artifacts. Such unstable nuclei decay into several decay products, each with significant kinetic energy. Which of the following is true? (a) The mass of the unstable nucleus is larger than the sum of the masses of the decay products. (b) The mass of the unstable nucleus is smaller than the sum of the masses of the decay products. (c) The mass of the

Question: What is the boldest and daring thing you have ever done in your life? I am going to state the most daring and boldest action which I had taken in my whole life. That action of mine is almost 1 year and few months old when I was in the first semester of MBA. I had worked for four months for an online company named as Xtraorbit360 whose work was to advertise the websites of different companies by posting their advertisement on free classified websites. I worked as a member for that company

light energy to energize electrons. While the end product may be different, solar cells and photosynthesis both utilize light energy for application. Solar cells and photosynthesis are very similar in how the utilize light energy. The purpose of both the solar cell and photosynthesis is to harness light energy and convert it into usable form. In a solar cell sunlight is absorbed by a semi-conductor. In plants “the pigments within the thylakoid membranes absorb solar (radiant) energy” (Mader

ABSTRACT Thermodynamics is the science of heat and temperature and, in particular, of the laws governing the conversion of thermal energy into mechanical, electrical, or other forms of energy. It is a central branch of science that has important applications in chemistry, physics, biology, and engineering. What makes thermodynamics such a powerful tool? It is a completely logical discipline and can be applied without any sophisticated mathematical techniques. The immense practical value of thermodynamics

Katarzyna Rutkowska, gr. 1 Commentary of 'Sun rising' by John Donne The poem 'Sun rising' written by John Donne is a kind of monologue in which the speaker adresses the sun. The speaker is probably a male who is lying next to his female lover: But that I would not lose her sight so long.[1] The poem is focused around the lovers' bed. The most important thing in this poem is addressee of the monologue – the personificated sun. The symbolic meaning of the sun is being intruder who disturbs

mass of the green one. Before colliding, the pucks approach each other with momenta of equal magnitude and opposite directions, and the green puck has an initial speed of 10.0 m/s. Find the speeds of the pucks after the collision if half the kinetic energy is lost during the collision. speed of Blue puck: 5.89 m/s Speed of Green puck: 7.069 m/s 2)The speed of a moving bullet can be determined by allowing the bullet to pass through two rotating paper disks mounted a distance d apart on

utilizing the kinetic energy of steam flow, the turbine could achieve a higher efficiency. As a result, the steam turbine has supplanted the reciprocating engine as a prime mover in large electricity-generating plants and is also used as a means of jet propulsion. The action of the steam turbine is based on the thermodynamic principle that when a vapor is allowed to expand, its temperature drops. In turn, its internal energy is decreased. This reduction in internal energy is transformed into

generators used in EDM Analyse working principle of RC type EDM generator 1. Introduction Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining process, where electrical energy is used to generate electrical spark and material removal mainly occurs due to thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high strength temperature resistant alloys. EDM can be used to machine difficult geometries in small batches or even on
